Young in Juvenal plumage .- — Female (No. 15,973, San Jos6 del Cabo, Octo- 

 ber 31, 1887). Above, including the crown, uniform pale wood brown, the 

 greater and middle wing coverts clayey buff; wings and tail light clove brown, 

 the quills edged with ochraceous, the tail feathers tipped with the same, form- 

 ing obscure terminal spots; middle of the breast and fore part of the abdomen 

 brownish white ; sides of the breast dull olive gray ; remainder of the under 

 parts rusty ochraceous, deepest on the under tail coverts, crissum, and flanks ; 

 Iniffy of throat bordered on each side by a dusky malar stripe which, above, 

 is separated from a still more obscure rictal stripe by a narrow interval of 

 bully; sides of the head uniform with the back; lores, however, distinctly 

 buffy ; a few obscure, dusky spots on the breast. 



In the specimen just described the feathers of the jugulum and breast seem 

 to be largely those of the first winter plumage. There are also a few feathers 

 of this plumage among the interscapulars, but otherwise the bird, although 

 taken so late in the season, is unmistakably in juvenal plumage. 



Another female (Triunfo, December 5, 1887), apparently a young bird in 

 winter plumage, has the spots on the jugulum as well defined as in many of 

 the spring specimens. The breast and a portion of the abdomen are also finely 

 spotted with dark brown, a feature which I do not find in any other example 

 in the entire series. This spotting is probably a characteristic of the juvenal 

 plumage which, in this individual, has reappeared in the first winter plumage. 

 It will be remembered in this connection that young in first plumage of the 

 allied forms P. /. mesoleucus and P. fusnis are rather thickly and generally 

 spotted over most of the under parts. The absence of these markings in 

 No. 15,973 is due, no doubt, as above suggested, to the fact that the feathers of 

 the breast had been already changed for those of the first winter plumage. 



Most of the autumnal birds in the series before me have the greater and 

 middle wing coverts tipped with ochraceous. In some of them the color of
